578-586 Guerrero St, San Francisco, CA 94110

The 6-unit, 3-story multi-family residential building at 578-586 Guerrero St, owned by Lee Shek Kwong and built in 1913, has undergone several significant safety upgrades in recent years. Most notably, the building completed mandatory soft-story seismic retrofitting in 2018 at a cost of $30,000, and recent fire alarm system upgrades in 2023-2024 to comply with fire code requirements, including the installation of low-frequency sounders in sleeping areas and updating existing devices for better compatibility with the fire alarm control panel. The building has one documented history of fire-related incidents, with three alarm activations since 2019, though none resulted in injuries or confirmed fires.

The property has experienced some maintenance and compliance issues over its history, particularly in 2002 when multiple violations were recorded, including problems with egress obstruction, fire proofing, and combustible storage, though all were abated by May 2002. A 2011 complaint regarding the annual alarm panel certification was also resolved. More recent complaints have primarily focused on construction activity, with reports in 2023 about construction noise and unauthorized work in March 2021, though both complaints have been marked as not active.

The building's recent permit history shows significant investments in safety improvements, including a $13,200 fire alarm system upgrade in October 2023, with additional electrical work completed in 2024. Planning records indicate installation of interior shear walls and window modifications, with a note regarding the legality of a rear addition allegedly constructed in 2003. Recent 311 calls have primarily concerned external issues such as parking violations and street cleaning matters.
